Normal control rats （group Ⅰ ） were given the vehicle oral dose of gum acacia in distilled water （1 mL per rat）; ulcerated control and treated rats （groups Ⅱ-V） were given a single dose of indomethacin （30 mg/kg body wt.）; group Ⅱ rats were sacrificed 4 h after indomethacin administration; groups Ⅲ-Ⅴ rats were given the vehicle （1 mL per rat） or APC （2 mg/kg body wt.） or misoprostol （1.43 μg/kg body wt.） once daily by oral intubation for 7 d starting from 4 h after the indomethacin administration. After 7 d, the stomach tissues were excised for histological examination and biochemical analysis. RESULTS： Treatment with APC （2 mg/kg body wt per day） and misoprostol （1.43 μg/kg body wt per day） for 7 d could effectively heal the stomach ulceration as revealed from the ulcer index and histopathological studies. Compared to the zero day ulcerated group, treatment with APC and misoprostol reduced the ulcer index by 93.4% and 85.4% respectively （P 〈 0.05）. Both APC and misoprostol accelerated ulcer healing observed in natural recovery （P 〈 0.05）, their respective healing capacities not being significantly different. The healing capacities of APC and misoprostol could be attributed to their antioxidant activity as well as the ability to enhance the rnucin content of the gastric tissues. Compared to the ulcerated untreated rats, those treated with APC and rnisoprostol showed near normal MDA levels, while the protein levels were 86% and 78% of the normal value respectively （P 〈 0.05）. Likewise, both APC and rnisoprostol increased the SOD, catalase, and rnucin levels significantly （P 〈 0.05）, the effect of APC being better. CONCLUSION： APC can protect indomethacin-induced gastric ulceration due to its antioxidative and mucin protecting properties.展开更多
Fourteen yearling standardbred horses were used to test the hypothesis that hay and grain fed as a complete total mixed ration （TMR） cube diet （C） would result in greater average daily gain （ADG）, feed efficien...Fourteen yearling standardbred horses were used to test the hypothesis that hay and grain fed as a complete total mixed ration （TMR） cube diet （C） would result in greater average daily gain （ADG）, feed efficiency （gain to feed ratio, G/F） and apparent digestibility in horses on the TMR diet compared to horses fed the same weight and proportion of hay cubes and grain fed separately （diet HG）. Both diets consisted of 75% forage and 25% ground oats. The forage in both the plain hay cubes and the complete cubes was 80% alfalfa and 20% endophyte-free tall rescue. An additional hypothesis that stomach ulceration would not differ between horses fed either of the two diet treatments was also tested by comparing upper gastric endoscopies before and after 70 days of feeding the experimental diets. Horses fed diet C had greater ADG （P 〈 0.046） while G/F between the two treatments was not significantly different （P 〉 0.065） but showed a trend to be higher in the horses consuming diet C. Apparent digestibility of dry matter and crude protein was not different between the diet treatments, and no major gastric ulceration was found in horses consuming either diet treatment. The results of this study found that a complete cubed diet of 75% hay and 25% oats did not cause stomach ulceration while achieving an acceptable growth rate in yearling horses.展开更多
